e*13 Helix R 11spd Cassette

Helix R 11-speed, 511% Range, 325-Grams

More Range, Less Weight
The HELIX R Cassette is an upgrade to any SRAM™ Eagle™ or Shimano™ drivetrain, with more range than any other cassette on the market. The 9 tooth cog lets you step down one chainring size while keeping the same top end gearing and provides not only better ground clearance, but an overall lighter drivetrain.

• Compatibility: Works flawlessly with Shimano™ and SRAM™ 11spd drivetrains, despite the challenges in designing for the different cog spacing and chain behavior. Additionally, if your wheel has a SRAM™ XD™ Driver and you want to upgrade to Shimano™ 12spd, you not only save money on the cassette and don’t have to spend the extra on a new hub driver. **Not recommended for e-bike use. For e-bike applications we recommend our TRS+ Espec cassettes.**
